Cannabis has shown potential benefits in the treatment of post-traumatic stress disorder (PTSD), a condition characterized by recurring distressing memories, anxiety, and other emotional symptoms following a traumatic event. While further research is still needed to fully understand its effects, there are several potential benefits associated with cannabis use for PTSD.

​​Firstly, cannabinoids found in cannabis, such as delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), can interact with the body's endocannabinoid system, which plays a role in regulating stress responses and emotional memories. This interaction may help modulate the fear and anxiety responses associated with PTSD, providing relief from symptoms.

Moreover, cannabis may help with managing nightmares, which are a distressing symptom of PTSD. Research suggests that THC can potentially interrupt the rapid eye movement (REM) sleep phase, reducing the occurrence of nightmares and improving sleep quality for individuals with PTSD.
